I created Spectrum because I wasn't satisfied with how other games handled time travel. Yes, you can travel anywhere and anywhen in time and space, but you can also do really weird things with time travel, like alter scenes already in play, meet yourself, call on your past or future selves for help, remember things that haven't happened yet, solve problems before they happen, and play events out of sequence.

Spectrum is GM-led, uses playing cards, and a simple core mechanic for physical and social interactions (card draw+Trait to achieve target number), to allow the players and the Guide to focus on the complexities of really detailed time travel.

I published Spectrum in 2013, and it's seen a lot of playtesting, so I won't consider this to be playtest. However, I do plan to try out a new demo scenario I've never run before. We'll be using pre-gen characters.

If you're interested in the game, but this slot doesn't work for you, let me know! I'd be happy to change slots to accommodate interested players.
